. Referring to Figs. 1 and 2, trackways 1 fixed above the top plate cotipera-te through anti-friction balls 2 with the slide bar 3 of a platen frame or carrier which further comprises end bars 4. Bearing in said end bars is the axle 5 of a rotary platen which comprises a core 6 and a sheath 7, said axle being provided at its ends with the usual finger wheels 5 A platen head 8 is suit- 5 ably secured to the right-hand end of the platen, while a line spacing ratchet wheel 9 is operatively connected with the left-hand end of said platen. A frame rod or bar 10 is arranged above the platen and is secured at its ends to the end bars at, said rod 10 providing a support for a pressure device or spring pressed bail like that disclosed in the Steele application aforesaid. Said pressure device comprises a rod 11 extending lengthwise of the platen above the printingline and secured at its ends to arms 12 provided with hubs 13 and finger pieces lat, the hubs bearing on the rod 10 and one of the hubs being connected with a spring 15 coiled soaround said rod 10 and secured thereto at one end, said spring tending to maintain the pressure rod 11 in cocperation withv the platen. The pressure device or bail is not claimed per se by me. My novel clamping devices comprise a plate 16 preferably formed of thin sheet metal, the plate extending partly around the platen and curved to conform generally to thesurface thereof. Considering the clamping plate to be positioned to receive the label or other work sheet as shown in Figs. 1

and 2, its lower" longitudinal edge or end portion is secured to the platen in any suitable way as by Wood screws 17. The clamp ing plate is cut out or slotted transversely as indicated at 18 to provide a setor series of parallel spring tongues or fingers 19 which extend upward transversely of the platen. The inherent spring in the metal 5 composing the clamping plate 16 is such that the tongues 19 will normallyengage with the platen surface and cocperate therewith with sufficient pressure to securely hold a paper label, ordinary card or the like.

In order to move the spring tongues 19 away from the platen so that the label may be inserted in position to be clamped, a rotary cam, rod or rock shaft 20 is provided, said rod being arranged between the clamping plate and the platen near the roots of the tongues 19 and extending transversely of said tongues and longitudinally of the platen. The left end portion of the rod or .shaft 20 is journaled in a lag 21 formed on an annulus 22 which'is fixed to the lefthand end of the platen, said annulus being arranged between the platenend and the line spacing wheel 9 and being preferably of the same diameter as the line spacing wheel. The right-hand end portion of the 7! rod 20 bears in a lug on a circular plate 23 which is fixed by screws 24 to the platen head 8. Preferably the end bearing portions of the rod 20 are reduced in diameter so as to provide shoulderswhich operate to prevent endwise movement of said rod in its bearings. The right-hand reduced portion of the rod 20 projects outside the plate 23 and carries a crank arm 25 having a hub 26 pinned at 27 to the rod. The crank arm is provided with a laterally projecting handle or finger piece 28 and at the opposite side of its axis is formed with two branches 29 and 30 which serve as stops, cooperating with a stud or stop 31 on the plate 23 to 5 limit theturning movements of the rod 20. Said rod is partly housed in a depression or groove 32 cut in the platen sheath 7 and is cut away at one side as indicated at 33 to provide a flattened surface. When the flat face 33 is turned to face outward toward the tongues 19 as indicated in Fig. 3, said tongues will engage with theplaten or the worksheet thereon because of their inherent I spring tension. The rod 20. is rotated to the 5 position shown in'Fig. 3 by swinging the finger piece 28 until the parts are arrested by the contact of the stop 29 with the stop or stud 31. By pulling the' handle 28 in the opposite direction until it is arrested by the engagement of the stop 30 with the stop 31, the rod 20 is rotated on its axis to bring. the curved or eccentric-like portion of its" surface into engagement with the tongues 19 as shown in Fig. 2. As this curved portion is farther from the axis of rotation than is the Hat 33, the rod will in consequence operate to open the clamp, that is, to cam or force the spring tongues away from the platen surface to the position shown in Fig. 2. Extending longitudinally of the platen, slightly below the free ends or tips :of the tongues 19,- is a slot or cut-out 34, said slot extending nearly through the platen'sheath 7. Near its ends the slot is enlarged; to provide holes 35 radial of the platen and which extend through the sheath and part way through the core 6. Arranged in the slot 34 behind the tongues 19 is a stop device or stop bar 36 rectangular in cross secs tion, shown detached in Fig. 4. Said stop bar is provided nearits'ends with angularly disposed "projections or guiding portions 37 which engage in the holes 35.- Surrounding the projections 37 and housed within the holes 35 are coiled springs 38 (Fig. 2), said springs tending constantly to force the stop bar 36 outward radially of the platen and to maintain said stop Preferably the "30. ranged on the platen by backward p the stop to earn the tongues receiving position as shewn in .stop devices which in the present instance bar in contact with the backs of the spring tongues 19 near the tips thereof. The spring tension of the tongues, however, normally overcomes the springs 38 and holds bar 36 housed within the platen But-when the handle 28 is turned 19 outward or away from the platen surface as shown in. Fig. 3, then the springs 38 will operate toforce the stop bar 36 outward o the position shown in said figure, from which it will be observed that the stop bar is thus adapted to surface.

' serve as a gage against which a label 89, card or the like may be positioned. The portions of the fingers 19 above the stop bar are the gripping or clamping port-ions, and the depths of these portions may 'e varied, as by changing the location of the stop bar, according to the character of the work sheet, a heavy work sheet requiring greater depth of clamping surfacethan alight, thin sheet. i

platen is positively arrest ed when it has been turned to bring the clamping and 'stop devices into initial or Fig. 2 by comprise, a radial projection 40 integral with they circular plate 23, said projection cotiperating with a spacing sleeve 41 arthe frame rod 10 and between the right-hand end bar 4 and the right-hand collar 13. Itwill be understood that prior to the insertion of the label 39 the pressure more or less from pressure applied to one of the finger pieces 14 and that after the label 39 has been inserted the pressure device is allowed to swing backso that the rod 11 engages the label as shown in Fig. 2. In some instances it may bemore convenient to insert a card or like work sheet by pushing it down between the platen and the rod 11 without first lifting said rod by h device 11 is swung away and.

After the label or work sheet has been positioned the finger piece 28 is pushed back, swinging the arm 25 rearward and turning the cam rod 20 to bring the fiat 33 opposite the clamping fingers '19 as shown in ig.

' 3, this movement permitting the fingers to return toward the platen and grip or clamp the lower edge portion of the label 39 as shown in Fig. 3. From observed that the stop bar 36 has been forced inward by the fingers. Itwill be seen that the stop bar though mounted on e the platen independently of the clamping der the control devices or fingers 19 will be at all times un of said fingers and that at times moveme ts of said fingers will be transmitted to said stop bar.-

After the label-.39 has, beerii-fotamped as described the platen may batu rued backthis figure it will be thelabel has been fed backward into position to receive the first line of print. lhe label or card will be held closely to the surface of the platen by the gripping tongues 19 at one of its edgesv and bythe pressure rod 11 at the opposite side of the printing line, so that thereafter as the label is printed and line spaced forward, it will always lie smoothly and snugly against the platen in the vicinity of the printing line, conduc ing to clearness o-revenness of type impression. The provision of the spring tongues enables the label. to be" gripped an held more securely than it would be if the clamping device were continuous through- .out the length of its clamping edge; Each tongue is in effect operate as such without regard to adjacent tongues. In other words, 't the label is short, one or more tongues may operate on it as clamps while the other tongues will beinactive, for that purpose. After the writing on the label has been completed it piece 28 forward, thus enabling the printed label to be removed and a fresh one inserted. In the modified construction shown in Fig. 5,the stop bar 36 is dispensed with and the cam rod is re-arranged in the space formerly occupied by said stop can The 39 may be adjusted. Afterward the clamp rod, designated as 42 in Fig.

may be closed by rotating the rod 42 as'in the prior construction.
